        * defaults.h (LOG2_BITS_PER_UNIT): Move from here...
        * tree.h (LOG2_BITS_PER_UNIT): ...to here.
        (BITS_PER_UNIT_LOG): Remove.
        (int_bit_position): Use LOG2_BITS_PER_UNIT instead of BITS_PER_UNIT_LOG.
        * expr.c (expand_assignment): Likewise. 
        * stor-layout.c (initialize_sizetypes): Likewise.
